Mr. Duncan,
Thank you for your response. I'll gladly do this tomorrow morning when I get back to the setup. Is there anything else you would like to see?
FYI, I've tried omitting the pull-down resistors on the gates of the transistors as well as the electrolytic capacitors I had in place between the rails for each half bridge and it seems to run better but it is still faulting out. I'll try 2.2 uF ceramic capacitors as the schematic for the DRV8303EVM shows and see how that affects the circuit.
I've noticed that both the nFAULT (from the oscilloscope images) and nOCTW (seemingly random) go low at times. Also, according to the schematic I posted, I do not have the current sense amplifiers connected to anything. Would this cause any problems with the circuit?
This is my first time working with this family of gate drivers and SPI communication, but I believe that I set the control registers according to the information on the datasheet. The settings may be an issue that I am overlooking.
